Can I Update iPhone 4S to iOS 8.4?

Last updated: July 1, 2015 at 1:01 am

Question: I have an Apple iPhone 4S old model with 16 GB storage space. I would like to know if I can install the latest iOS 8.4 firmware on it?

Because for me iOS 8.3 on iPhone 4s is buggy and slows down multitasking. Apps also crashes… making the phone almost unusable. Can we get the latest iOS 8.4 update to iPhone 4S?

Answer: When Apple announced iOS 9 this year, at the WWDC event, it was said that all the devices supporting iOS 8 firmware will get iOS 9 update.

In simple words, if you have iOS 8 on your device, then you will definitely get iOS 9 when it is released this fall (in the 3rd week of September, 2015).

As it happens, I also have an Apple iPhone 4s with iOS 8.3 update. Because Apple released iOS 8.4 update – I chose to upgrade the device and I am yet to see any substantial issues so far.

Haven’t seen any apps crash yet, but the lag (slowness) is common with apps and games.

And we all know that Apple iPhone 4s is an old device. It is still receiving new iOS updates is actually a good thing. I have also mentioned in my iOS 8.4 article that iOS 8.4 comes with a set of problems – all of them are now common to most of us.

In short, to answer the main question – YES, you can get iOS 8.4 update on your iPhone 4s right away. And it doesn’t matter if you are using iOS 8.1, or iOS 8.2 or iOS 8.3 – as long as you have iOS 8.x… you can jump directly to iOS 8.4 without any problems using these installation methods.
